Antiinflammatory effects of some copper complexes.
    Journal of medicinal chemistry, 1980, Volume: 23, Issue:7

    Copper complexes of a range of ligands have been prepared and evaluated for antiinflammatory activity and irritancy after oral, subcutaneous, and local administration in rats and guinea pigs. The antiinflammatory activities were found to depend on the species used and the route of administration. When nonantiinflammatory ligands were used, the response was generally dose dependent. With D-penicillamine and when the ligands were themselves antiinflammatory in animal models of inflammation--as was the case with flufenamic acid, levamisole, aspirin, L-histidine, and 2-amino-2-thiazoline--differences in antiinflammatory activity were observed between the copper complexes and the free ligands. In some cases, the copper complexes were the more effective. There was a weak correlation between local (subplantar) irritation and the dose of copper but, for four compounds studied in more detail, the response in the local subplantar test and degree of antiinflammatory activity were not related, suggesting that the action of copper is not solely by a counterirritant mechanism. No obvious differences between the activities of copper(I) and copper(II) compounds were observed, suggesting that a common metabolite may be involved in the antiinflammatory action of copper.

Comparative effects of drugs on four paw oedema models in the rat.
    Agents and actions, 1979, Volume: 9, Issue:1

    The development of novel anti-inflammatory drugs (AID) has been claimed to be dependent on the discovery of models of inflammation that differ from those currently used for drug screening, e.g. carrageenen paw oedema and u.v. erythema. We have thus evaluated the effect of a variety of drugs in a number of novel models of inflammation in the rat produced in the hind paw. We have utilized kaolin, zymosan, anti-rat IgG (anti-IgG) and the Reversed Passive Arthus (RPA) reaction to produce these oedema models. We found that the non-steroidal AID's, e.g. aspirin, flufenamic acid, indomethacin, naproxen, and phenylbutazone, were active in all four tests. Of the nine novel AID examined, levamisole and tetramisole demonstrated considerable activity in all four tests and dapsone was especially active in the anti-IgG and RPA tests. In contrast, the anti-rheumatic d-penicillamine was inactive in all four models. Each of the ten compounds tested which has been claimed to influence complement function, was active in the RPA but not in the kaolin model. These results are discussed in the context of the aetiology of each oedema and the suspected mode of action of the various drugs.

1,6-Dimethyl-4-oxo-1,6,7,8,9,9a-hexahydro-4H-pyrido [1,2-a] pyrimidine-3-carboxamide (Chinoin-127), a potent non-narcotic analgesic and antiinflammatory agent.
    Arzneimittel-Forschung, 1979, Volume: 29, Issue:5

    1,6-Dimethyl-4-oxo-1,6,7,8,9,9a-hexahydro-4H-pyrido[1,2-a]pyrimidine-3-carbamide (Chinoin 127), a non-narcotic analgesic with potent antiinflammatory activity is described. Chinoin-127 is more potent as an analgesic in the hot plate, Randall-Selitto and writhing tests than is acetylsalicylic acid (ASA) and an effective antiphlogistic agent in a battery of tests (carrageenin, kaolin and dextran induced rat paw edema, Northover test, carrageenin induced abscess, implanted cotton pellet method, adjuvant arthritis) used for measuring antiinflammatory activity. The PG-synthesis inhibitors (indometacin, suprofen) were found to be devoid of analgesic activity, and great test-dependent variations in their antiinflammatory effect were observed. They proved to be inactive in the Northover test. Unusual grade of inhibition in the carrageenin-induced rat paw edema test was obtainable by the simultaneous administration of Chinoin 127 and indometacin.
